Disclosed is a multi-stage planetary vehicle transmission comprising a housing (9) in which four planetary gear sets (RS1, RS2, RS3, RS4), a plurality of shafts (1, 2, 3, 4, 5, 6, 7, 8, 8A, 8B, 8C, 8D) , and six shifting elements (A, B, C, D, E, F) are arranged which allow a plurality of gear stages to be implemented upon actuation thereof. The first shaft (1), as an input element (An), is directly connected or can be indirectly connected to the sun gear (SO3) of the third planetary gear set (RS3), can be indirectly connected to the sun gear (SO1) of the first planetary gear set (RS1), can be indirectly connected to the planet gear carrier (PT1) of the first planetary gear set (RS1), and can be indirectly connected to the annulus (SO2) of the second planetary gear set (RS2). The second shaft (2), as an output element (Ab), is directly connected to the annulus (HO4) of the fourth planetary gear set (RS4) and is directly connected or can be indirectly connected to the planet gear carrier (PT3) of the third planetary gear set (RS3). The sun gear (SO1) and the planet gear carrier (PT1) of the first planetary gear set (RS1) as well as the sun gear (SO4) of the fourth planetary gear set (RS4) can each be connected to the housing (9), the annulus (HO1) of the first planetary gear set (RS1) being connected to the planet gear carrier (PT4) of the fourth planetary gear set (RS4) and being connectable or connected to the annulus (HO2) of the second planetary gear set (RS2), and the planet gear carrier (PT2) of the second planetary gear set (RS2) and the annulus (HO3) of the third planetary gear set (RS3) being connectable or connected to one another. |
